COMBINED TOILET FLUSH -AND INTAKE VALVE.

Application filed July 29, 1924. Serial No.v 728,860.

To all whom. t may concern:

Be it known that I, CHARLES H. GUNN, a citizen of the United States,residing at Oakland, county of Alameda, vState of C-aliiornia, haveinvented certain new and useful Improvements in Combined Toilet Flushand Intake Valves; and I do declare. the following to be a full, clear,and exact description oit the same, reference being had to theaccompanying drawings, and to the characters of reference markedthereon, which form a part oli this application.

This invention relates to the plumbing art and particularly to flushvalves and operating apparatus therefor used in connection with toiletsof all kinds.

The present, application includes improved details oi' construction overthe apparatus shown in my copending application for patent, Seria-l No.720,211, tiled June 16th, 1924, the object of the present inventionbeing to render the valve action much morel simple` and eflicient. andalso to allow the seat and seatcover to be of common constructionwithout interfering with the operating mechanism.

A further object is to avoid the necessity of having any spring closurecontrol for the valves which will eliminate any possibility of the samebeing subject to leakage.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of rei erence indicate correspondingpart-s in the.

several views:

Fig. 1 is a side elevation oit the complete apparatus as installed inconnection with the toilet.

Fig. 2 is a top plan view of the same.

Fig. 8 is a vertical section of the complete Fig. 4 is another verticalsection oi the valve taken at right angles to the section shown in Fig.3.

Fig. 5 is a sectional view taken on a line 5 5 of Fig. 3.

Referring now more particularly to the characters of reference on thedrawings, the numeral 1 designates the toilet which is of usualconstruction. and having the usual hinged seat 2;

The numeral 3 designates the pressure tank connected with the bottom ofwhich is my improved valve ceastructon which includes the valve casing4, having open communication at its upper end with the said tank. Hthinthe casing 4 is karranged a valve housing 5 formed in the bottom or'which is the valve seat 6 surround ing port i' connnunicating from thehouse ingl 5 into the casing 4. An inlet pipe S leads from the source ofwater pressure supply, such as the city main or the like, into thehousing 5.

The numeral 9 designates the centrally ported diaphragm arrangedsubstantiall)r midway of the casing 4 and having a valve seat 10surrounding its port 91.

The numeral 11 designates a valve stein slidable in a central guide 12and 'extending through the central port 9a of the diaphragm 9 andthrough the port 7. As will be noted, the valve seats 6 and 10 arepositioned in opposed relation with respect to each other. On the stem11 adjacent the two valve seats 6 and 10 are meta-l shells 13 and 14respectively, in which are seated valve gaskets 15 and 16 of rubber orother desired material arranged for engagement with the respective valveseats to form closures for the ports, as and for a purpose as will bepresently pointed out.

The distance between the gaskets 15 and 16 is slightly greater than thedistance between-the valve seats 6 and 1() so as to allow the alternateopening and closing of. the ports 7 and 9a. The valve stem 11 has'anextension 11"1 provided with a transverse slit 11b in which projects thecam 17 mounted on the arm 18 keyed to the shaft 19, which is journaledin the side of thecasing 4 and has on its outer end outside the casing`4 thev lever 20. Y

A supporting plate 21 is bolted to the sta-- tionary part of the toiletby` cap screws 22 and supports the valve structure just described. Thesecap screws'are standard on all modern toilets and serve to secure thehinge structure of the seat to the bowl. This plate is provided with apair oflugs 23 between which is pivoted a lever 24. At one end of thislever 24 is an adjustable screw 25 arranged for engagement with thelever arm 20, while the opposite end of the lever 24 projects underneaththe hinged seat 2 for contact with a plate 26 secured to the said seat2.

On the lower end of the extension 11a of the valve stem 11 is a coilspring 27. This acts to normally hold the Stem 11a down againstv the cam1.7 which in turn forces the lever arm 20 to engage the screw 25 andpress the lever 24- down at that end so that its opposite end engagesthe plate 26 and holds the seat 2 in slightly elevated position, asshown by dotted lines in Fig. 1. ln this position the water pressure inthe housing 5 is trapped therein and holds the valvel 15 closed againstits seat 6 so that no water can escape into the easing 4.

When a person sits on the seat 2 the weight moves the seatclow/'iiwaidl-y and presses the leve-r 24 to lift the arm 20, Thisthrough the medium of the shat 19, arm 18, cam 17 and extension 11alifts the valve stem 1l and brings the valve 16 into closed positionagainst its seat 10 and simultaneously lifts the valve 15 from its seat6. lVater then flows through the port 7 into the tank 3 until the airpressure in the tank equalizes the same, whereupon this conditioncontinues until the weight of the user is removed from the seat 2. Assoon as this weight is removed the water pressure in the tank 3 actsagainst the valve 16 and. forces that valve open and closes the valve15. Thereupon the water under pressure in the tank 3 flushes out throughthe port 9 and thro-ugh the open end 2S of the casing 4 and through'theflush pipe 29 into the toilet 1, there serving its usual function. lVhenthis is accomplished the spring a7 has sufficient tension to hold theseat 2 partly open, as has already been described, and this device isagain ready for functioning upon any further persons sitting upon thesaid seat.

The water pressure desired for the Vflushing .operation may be adjustedby the relative positions of the gaskets 15 and 16,

From the foregoing description it will be readily seen that I haveproduced such a device substantially fulfills the objects of theinvention set forth herein.

lVhile this specification sets forth indetail the present and'preferredconstruction oic the device, still in practice such .deviations fromsuch detail may be resorted to as do not form a departure from thespirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim'as new and useful anddesire to secure by Letters Patent is:

1. A toilet flush comprising a casing adapted at its upper and lower.ends liofr lessees@ direct connection to a tank and a toilet llush piperespectively, a water intake pipe, a chamber in the casing to which saidpipe leads, said chamber extending transversely of the casingintermediate the ends thereof and not interfering with the iree passageof water from one vend oi the casing to the other, a transverse andoriiced wall across the casing below the chamber, the latter having anorifice iny its lower side disposed in vertical alinement with said wallorifice, and valves for said ol'ces mounted in common and adapted to bemoved to alternately close the orifices, the valve for the chamberorilice being inside the chamber and closing with a downward movement,whereby water pressure in said chamber will not tend to open the valve.

2;. rlhe combination with a toilet comprising a bowl, a seat hingedthereon and screws securing the hinge to the bowl; of a flush valvestructure mounted in connection with the bowl, a horizontal operatingarm project-ing from the structure, a lever having one end under theseat and the other end under the outer end of the arm, and means forpivoting the lever onto the bowl in connection with the seat-hingescrews.

3. The combination with a toilet comprising a bowl, a seat hingedthereon and screws securing the hinge tol thebowl; of a flush valvestructure mounted in connection with the bowl, a horizontal operatingarm projecting from the structure, a lever having one end under the seatand the other end under the outer end of the arm., and a plate securedon the bowl by the seat hinge screws, the lever being pivoted on theplate.

4. The combination with a toilet comprising a bowl, a seat hingedthereon and screws securing the hinge to the bowl of a -flush valve streture mounted in connection with the bowl, a horizontal operating armprojecting lfrom the structure, a lever having one end under the seatand the other end under the outer end of the arm, and a plate onwhiehthe lever is pivoted', secured to the valve structure and to the bowl byvthe seathinge screws, whereby to maintain said bowl, valve structureand lever in deinite positions relative to each other..

In testimony whereof l allix my signature.
